Description

Technical Field

[0001] The invention relates to a stick-shaped object storage device, in particular to a stick-shaped object storage device with variable volume and first-in-first-out function, belonging to the technical field of tobacco processing. Background Art

[0002] In a cigarette production line, one or more buffers need to be arranged between the upstream cigarette forming equipment and the downstream cigarette packaging equipment to balance the normal production of the upstream and downstream equipment. That is, when the downstream cigarette packaging equipment fails or stops, in order not to affect the normal production of the upstream cigarette forming equipment, the produced cigarettes need to be sent to the buffer for temporary storage to maintain the normal production of the cigarette forming equipment; when the upstream cigarette forming equipment fails or stops, the buffer will provide cigarettes to the downstream cigarette packaging equipment to ensure the normal operation of the cigarette packaging equipment. The buffer in the prior art is divided into two caching methods: one is the first-in-first-out caching method, which is called the first-in-first-out caching method; the other is the first-in-last-out caching method, which is called the first-in-last-out caching method. Among them: the first-in-last-out caching method will cause the first cigarettes deposited to stay in the buffer for a long time, so that the special flavor cigarettes will reduce the original aroma of the cigarettes due to long-term retention. Therefore, this type of cigarette is not suitable for the first-in-last-out caching method.

[0003] Although the first-in-first-out caching method has gradually become the preferred method for tobacco production, the first-in-first-out caching equipment currently on the market is usually accompanied by the problem of occupying a large overall space, and reducing the occupied space will also lead to the problem of a smaller cache capacity. In addition, the existing cache has many disadvantages in terms of spatial layout, flexible disassembly, transportation or production and storage requirements, which has long plagued the production of production enterprises. Therefore, it is necessary to improve the existing technology. Summary of the invention

[0004] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a stick-shaped object storage device with variable volume and first-in-first-out function.

[0005] The present invention is achieved through the following technical scheme: a variable-volume, first-in-first-out storage device for rod-shaped objects, including a cabinet with an inlet and an outlet, characterized in that a plurality of layers of conveying channels are arranged on the cabinet, and every two layers of conveying channels are composed of two symmetrical conveyor belts, the head ends of the two conveyor belts are arranged in parallel with the head ends, and the tail ends are arranged in parallel with the tail ends, and one head end and the other tail end of the two conveyor belts are respectively connected to blanking baffles with grooves on the inner sides thereof that move toward each other, and the grooves on the inner sides of the blanking baffles that move toward each other are relative and staggered up and down, thereby forming two groups of blanking baffles that move toward each other on the cabinet, and as the two groups of blanking baffles move toward each other, an S-shaped blanking channel with a reduced width or an S-shaped storage channel with an increased width is formed in the longitudinal direction of the cabinet.

[0006] The two groups of blanking baffles moving toward each other are respectively connected to the corresponding vertical slides, and the two vertical slides are respectively screwed to the corresponding two or the same horizontal screw rods through corresponding nuts. One end of the horizontal screw rod is connected to the seat bearing, and the other end is connected to the power machine, so that the horizontal screw rod can rotate under the drive of the power machine, and then drive the two nuts, the two vertical slides, and the two groups of blanking baffles to move synchronously and toward each other along the horizontal screw rod, so as to realize the width adjustment of the S-shaped blanking channel.

[0007] A plurality of guide blocks are arranged at intervals on the vertical slide, and the plurality of guide blocks are slidably connected to corresponding guide rods fixed on the cabinet body, so as to determine the movement direction of the vertical slide and ensure the stability of the width adjustment of the unloading channel.

[0008] Among the several layers of conveying channels, material conveying and storage channels are formed between every two layers of conveying channels.

[0009] The cabinet body is two back-to-back rectangular columns, or a plurality of back-to-back polygonal columns, or a plurality of parallel rectangular columns combined into one body, or a cylindrical column.

[0010] The present invention has the following advantages and effects: adopting the above technical scheme, the width of the material storage channel can be easily increased according to storage needs to expand the storage capacity, or the width of the material storage channel can be reduced to reduce the storage capacity until it becomes a channel for unloading only, and after the material enters, it can only be stored from top to bottom in sequence, so it can only be sent out in sequence from the lowest outlet, realizing a first-in-first-out storage mode, not only with a simple structure and flexible width adjustment, but also with stable and reliable performance, especially it can be extended longitudinally, increasing the storage capacity while not occupying space. It is indeed an ideal storage device for rod-shaped objects. BRIEF DESCRIPTION OF THE DRAWINGS
